In this video, race car driver Scott Pruett and BMW Product & Technology Communications Manager Matt Russell explain the BMW M Electronic Damper Control (EDC) system and how the Comfort, Sport and Sport+ suspension settings make a difference in the F10 M5 and F12/F13 M6.

Although the M5 and M6 use an M tuned version of the BMW EDC, here is a general summary of EDC technology
from BMW:

Electronic Damper Control (EDC) automatically or manually adjusts each damper to suit the driving conditions meaning you enjoy outstanding comfort along with the best in BMW on-road safety. EDC reduces variations in wheel load, ensures tyres have excellent traction and counteracts bodyshell movement regardless of the weight your automobile may be carrying or the state of the road's surface.

Sensors constantly monitor all factors influencing the vehicle's behaviour and occupants' comfort, in order to precisely adjust the damper control. In a fraction of a second, the signals are analysed by the EDC microprocessor and orders are sent to the actuators on the shock absorbers, which, with the help of magnetic valves, are variably adjusted to provide optimal suspension. Thanks to Electronic Damper Control, the tendency for the nose to dip when braking is practically eliminated. The influence of potholes and unevenness on the road surface is reduced to minimum.

In addition to increased driving comfort and improved roll characteristics on the tyres, EDC also contributes to vehicle stability and safety. By reducing the nose's tendency to dip when braking and improving the tyre traction, EDC shortens the braking distance when braking heavily. The damper adjustment means that even when braking with ABS the vehicle chassis remains upright on the road and all four wheels have the largest possible contact to the surface.

The Driving Experience Control switch with ECO PRO lets the driver choose between various programs (like COMFORT, NORMAL, SPORT or SPORT+) and adjust the suspension to suit his individual needs.

So, am I correct in assuming that this is only changing the rebound settings on the dampers?

It changes both compression and rebound, and each setting has its own variable map. If you search for the EDC technical document, it explains EDC in extreme detail; everything from wiring diagrams to the location of all the sensors used for EDC control.

Seems like this info would also be applicable to the Adaptive M-suspension option available as part of the Dynamic Handling Packaging for the F30?

Yeah, it's the closest they've got. I've driven the CTS-V, and their suspension is quite good for city driving. Never been on a track with it.

I've been wondering the same thing, it seems like M Adaptive suspension on the F30 should be the same thing but BMW seems reluctant to confirm (they did rename the system to EDC on the M cars so maybe they're trying to protect its prestige and make it seem like a more advanced system?

Also, I briefly drove a friend's CTS-V in its "track" suspension mode and felt it to be too soft and a little underdamped. It was superb for cruising around but didn't tighten up enough when we were really attacking a bumpy back road, it was a little too floaty and bouncy. That car had 20,000 miles on it so maybe the suspension is a little worn out, I don't know. In my opinion, comparing that CTS-V to the E90 M3 my brother had with 35,000 miles on it I vastly prefer EDC. It's not as comfortable, but it's so much better for the track or for bumpy back roads.

Actually the E30 M3 had it
Not sure why Cadillac makes it sound like they invented it
As far as I know it was lotus that first did testing on it
Unless they took it with them during the time they owned lotus, then sold lotus and kept it

Is this different than the EDC that comes with the Competition Package on the E90/92/93 M3?
